Id' be surprised if your party doesn't already have someone that can use a wand of cure light wounds (ranger or paladin?). However here are some options (some of which were already mentioned):
1) UMD a CLW wand
2) Become a rogue/bard arcane trickster
3) Take a level in cleric; just the domain abilities can make it worthwhile (magic or luck are useful)
4) Convince another party member to obtain a level in cleric for the same reasons
5) Take a level in Paladin, ranger, bard or druid
6) Convince another party member to obtain a level in Paladin, ranger, bard or druid
